A MATLAB code for fingerprint enhancement.

< 深入浅出MATLAB 7_X混合编程>>电子书,系统介绍了matlab和其他语言的混合编程,和交互接口,如C/C++ fortran等!深入浅出,很值得推荐()

说明：  对于已定义的包含从0到15的整数的列向量xsym，就可以利用modem.qammod对象的modulate方法来调制它。其中M值为16，亦即为码字表的大小。 对已调制信号可采用awgn函数添加加性高斯噪声。其中比特能量与噪声功率谱密度的比值，Eb/N0，设置为10dB。 (The method comprising modulate integer from column vectors xsym 0 through 15, can use the defined object modem.qammod modulating it. Wherein M is 16, i.e., a codeword size of the table. Modulated signal can be used for awgn function to add the additive Gaussian noise. Wherein the ratio of bit energy to noise power spectral density, Eb/N0, is set to 10dB.)

扩频通信系统仿真 ——系统将基带信号（即信息）的频谱扩展至很宽的频带上，然后再进行传输，即将欲传输的信息数据用伪随机序列编码调制，实现频谱扩展，然后通过信道编码发送出去；接收端采用与发送端完全相同的伪随机序列作为本地解扩信号进行相关处理，以恢复信息，最后进行解调，完成整个系统的接收。(Simulation of spread spectrum communication system- the system baseband signal (ie, information) be extended to a wide spectrum of frequency bands, and then transferred, will want to use transmitted information data sequence of pseudo-random code modulation, to achieve expansion of the spectrum, and then sent channel coding receiver and transmitter use the same pseudo-random sequence as related to the local despreading signal processing, in order to restore the information, the final demodulation, the receiver to complete the system.)

关于ALOHA协议的M文件，将无捕获效应仿真结果,无捕获效应理论值,有捕获效应仿真结果进行了比较(ALOHA protocol M-file, will not capture the effects of simulation results capture the effect of the theoretical value, capture the effects of simulation results were compared)
